"The Purple Cow" Reflections on a Mythic Beast

I never saw a Purple Cow;
I never hope to See One;
But I can Tell you Anyhow,
I'd rather See than Be One.
Gelett Burgess

I have always enjoyed this poem but it is a little odd( but just a little). I think there might be a hidden meaning somewhere in this poem. Maybe if we took all the capital letters it would tell us some truth; I P C I S O B T A S B O humm... interesting what does this mean?

Post Script: If anyone wants to give me a Milka bar I would be totally alright with that.
